Jerome approved of Obutsu's weapon choice as he pulled out another magazine for his rifle.  Getting low, he thought.  Hadn't really expected to need to use as many rounds as this was needing, but there was nothing for it.  Going to need to pick his shots from here on in.

"Your Djinnery worked well Blue! Keep it up, apparently its pretty stupid."   A contingency plan involving Tom and a demo charge was forming in Jerome's mind.  "Tom, grab package #1 and get ready to move."

Jerome had been careful not to install a full AI in Tom and Jerry.  The programs were good, but lacked agency.   Even then, they had occasional odd outbursts that made him wonder. 

"Blue, you want me on the gun so you can focus on Dijinnery?"

G'day
I currently have 3 whole worlds that I operate in.
For decades I have been developing KININ, a full spectrum D&D world. In this world, anything goes. Almost every option from any legit source, and many from third party appear in this world. I have run it, 2nd, 3rd, 3.5, and now 5th. I am currently migrating the whole thing to Obsidian Portal.

There you will also find HAMON. Which is inspred by the Conan stories by Robert E. Howard and Elric stories by Michael Morcock. A primal world of low magic and High Aventure. I am also building a Hamon Sourcebook on 5e Homebrewery.

I look forward to sharing these with you.

The decrepit infested Gladiator lumbered forward, Blue's psychic conduit glowing luminous in front of it. It's cilia waved excitedly. Rockets punched into the old armor around the machine's knees. The armor plate on the left knee buckled, exposing the rusted ruin of the knee actuator, and the fibrous tendrils of alien matter wrapped around them. A fluid somewhere between blood and motor oil erupted from the joint, and it obviously displeased the thing as it made a weird chittering grating noise inside the mech torso. It slowed its pursuit as it was seemingly capable of feeling pain. Blue's rusted iron lance struck true, smashing through what little remained of the cockpit before glancing down and penetrating into the torso. The cilia that weren't crushed or sheered off by the hunk of tetanus retracted into the armor shell and more of the weird blood oil ran down from the neck hole. Angered and injured, the monster struck into the side of the hulk that the spear came from, shaking it. Pieces of metal started raining down around it.

LV screamed inside the cargo bay, obviously distressed by the psychic noise that the monster was making, and possibly by the fact that she was being pelted with a stream of spent shell casings and exhaust from rocket rounds.

The turbo tank has a 20mm cannon with standard explosive rounds

DM Suggestion: called shots, and aimed shots.

I like the idea of going TK, and would suggest exploiting the surrounding terrain. You and the monster are in the midst of rusted metal hulks and wreckage from massive construction projects two centuries past. Lots of jagged metal, beams, etc
